My Technology Adventure

I want to try make a remote control car by Raspberry Pi. The first question is how to power a portable Raspberry Pi? There are lot of solutions in internet. I want to find a simple, cheap and long battery life solution. Some articles introduced power bank but it overs $100 and only provides 5v output. I need some thing can provide not only 5v power for Raspberry Pi, but also more than 7v for L298N.

Cisco UCS blade system is the best blade system I used so far. Whatever the hardware, software or support is perfect. I recommend leverage the system for primary system of virtualization. UCS blade system architecture is different with HP. I feel it more likes a network system. Fabric Interconnect (FI) modules exchange data between uplinks and internal components. IOMs on each chassis controls data routing. Architecture is complicate, but it’s powerful to manage large datacenter. Talking about large datacenter, you may have hundred chassis or blades. Data goes through FIs, IOMs and blades, you could see issues on any layer. It’s hard to find out where exactly the problem is. UCS Manager provides statistics for ports just like how Cisco does on network switches. You can show statistics of a particular port. But it doesn’t tell you when and which layer it happened. I tested Cisco UCS adapter for vRealize Operation Manager before I reviewed NetApp adapter for vRealize Operation Manager. It’s developed by same company Blue Medora. I’d like to introduce few of this product, it’s just my personal review.
